- Specification forming" part of Letters Patent No; 57,932, dated September 11, 1866.

. To all whom it may concern:

Be it known that I, J. FRED. LLnwnLLYN, of Louisville, J efi'ersou county, State of Kentucky, have invented a new and useful In provement in Condensers for Druggists and others; and I do hereby declare that the following is a full, clear, and exact description thereof,,'wl1ich will enableothers skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is an under-side viewof an apparatus made according to myinvention. Fig. 2 is. a vertical section taken in the plane indicated by the letters at of Fig. 1. 1

Similar letters of reference indicate like part-s.

. The object of this invention is'to provide a condensing apparatus for the use of druggists and others in evaporating alcohol from extracts, tinctu'res,-or other alcoholic prepara-Q tions, or from wasteor dirty alcohol.

It consists, in general terms, in a deep ves sel, whose sides are provided with oneor more inclined gutters, the gutters being provided with outlets at-the place of their lowest depression. This vessel is inverted over an evaporating-pan or over the liquid to be evaporated, and upon it, when inverted, is formed a refrigerating-chamber, open or closed, as dcsired, into which ice or any othei refrigeratin g substance is'placcd, so as to cool the upper surface of the condenser. v

In the example here given of my invention, A designates the condenser. Its top issolid, and its lower side is open. Its form is circusemble a truncated cone; Its shapeinay,

however be varied to suit the convenience or udgment of the operator.

The upper part of the condenser is inclosed by an open cylinder, dered or otherwise secured water-tight to the sides of the condenser alittle distancebelow. its top-'say, about one-third'of its whole heightits upper-edge risin g about the same distance above, and so forming a refrigerating or ice chamber,- E', on the top of the condenser.

Since the sides of the condenser are conical and theinclosing body is cylindrical, it follows that a continuous space, G, will be left between.

top, so as torewhose lower edge is sol-.

them about the'npper part of the sides of the condenser.

The condenser here shown'has two parallel inclined gutters within it against its sides, to wit, an upper one, B, and a lower one, D, both inclined in the same direction. The upper one, B, is about opposite the bottom of the re frigerating-space G, and its :lo'west sideco1n municates with a pipe, which terminates just above the lower gutter, D. i

' The gutter D is emptied by a pipe, E, which passes through the sides of the "denser at the lowest point of said gutter, a dseonducts the products of condensation to-anyvessel or receiver which may be provided. p

Within the mouth of the condenser, at'a suitc ble height above its edge, I provide a led ge or 'gu tter, H, which is parallel with such edge. and on which the condenser may be supported by fitting or resting on the edge or rim. of an evaporating or other pan or vessel, which contains the mixture or preparation from which alcohol or other volatile liquid is to be sepa rated byevaporation,

The condenser is used in the following manner: The condenser having been placed over an evaporating-pan containing any alcoholicv preparation, ice and salt or other refrigerating mixture is put into the vessel As the ice melts, the cold water runs down into the narrow surrounding space G, thereby cooling the i of the condenser, as well-as the top, and causing arapid; condensaupper part of the sides tion of the alcoholic vapors which rise within the condenser, the condensed liquid running down the sides thereof into the troughs B D,

that which falls into the trough B running toward 'the' mouth of pipe 0, and thence into trough D, whence it escapes from the condenser into pipe E. ,As the water in the space G rises in temperature it becomes displaced .by the cold water from the melting ice, and consequently the sides of the condenser and its top are kept cool, the water which has become comparatively warm rising toward the top of vessel F,- whence it may be drawn off by a pipe.

It will be observed that "this construction prevents the return of alcohol t-o'the evaporating-pan, and

needs no watching while in operation.

This apparatus will be found very useful in and others in separating alcoholand other "01- eonneotiou'with evaporating-pans where alco- :mt-ile liquids, constructed and operated 'Sllbho] is being slowly evaporated, as inmaking stantiall y as above set forth. fluid GXlJI'QCtS, eoncentmtiiie' tinctures or reotii v FT.?T. fymg waste or dirty alcohol, J FRED Vhat I elaimlas new, and desire to secure Witnesses:
